A system and method are provided for actively illuminating and capturing images of an object, such as a driver of a vehicle to reduce glare. The system includes a video imaging camera orientated to generate images of the subject object (e.g., eye(s)) in successive video frames. The system also includes first and second light sources operable to illuminate the object one at a time. The system further includes a processor for processing the image by performing pixel-wise min operation to combine multiple frames into a single frame to reduce glare in the image. The system may remove glare caused by the illuminators and caused by external energy sources.
